碩士 === 國立高雄科技大學 === 環境與安全衛生工程系 === 107 === According to the rapidly population growth and economic development, the demand of petrochemical materials is increasing, and ethene and propene are one of the most significant materials, it is also an important indicator to measure the scale of petrochemical industry. This research used discarded Pt catalyst and Ni catalyst to produce ethene and propene by microwave, due to the characteristics of the coke that contained in catalyst, which is absorb the microwave then transform into thermal energy as the energy that it needs for reaction. We set the microwave power at 450 W, Propane/ Feed volume ratio=10:10 mL/min, total timing is 60 minutes. The result shows that with discarded Pt as catalyst (6g), the yield rate of ethene, propene, and hydrogen were 15.5%, 34.4%, and 26.9%. Besides, with discarded Pt catalyst (6g) mix Ni catalyst (2g), the yield rate of ethene, propene, and hydrogen were 1.9%, 23.2%, and 60.5%. On the other hand, we feed hydrogen in the same microwave condition, the recruitment of hydrogen is (C3H8+H2, add 10% of hydrogen in Propane): Air volume ratio=10:10 mL/min. The result shows that discarded Pi as catalyst (6g), the yield rate of ethene, propene, and hydrogen were 18.5%, 19.7%, and 32.9%. Moreover, with discarded Pt catalyst (6g) mixed Ni catalyst (2g), the yield rate of ethene, propene, and hydrogen were 3.6%, 15.8%, and 53.3%. We added hydrogen in coke to retard the form of catalyst surface coke. The coke content of discarded Pt catalyst is 5.3 wt% (add H2) v.s. 6.3 wt% (no H2), and the coke content of discarded Pt catalyst mix Ni catalyst is 5.5 wt% (add H2) v.s. 6.3 wt% (no H2). This research used the technology of discarded Pt catalyst and Ni catalyst produced ethene and propene by microwave, not only produce High value gas (ethene & propene), but also high yield rate of hydrogen, and reuse the discarded catalyst to implement recycling the waste resource.
